when a stone falls freely, the time taken to hit the ground varies as the square root of the distance fallen. If it takes four seconds th fall 78.4m, find how long would it takefor a stone to fall 500m

The stone would take approximately 10.107 seconds to fall 500 meters.

Step-by-step explanation:

According to the statement of the problem, the following relationship of direct proportionality is built:

Where:

- Time spent by the stone, measured in seconds.

- Height change experimented by the stone, measured in meters.

- Proportionality constant, measured in .

First, the proportionality constant is determined by clearing the respective variable and replacing all known variables:

If and , then:

Then, the expression is . Finally, if , then the time is:

The stone would take approximately 10.107 seconds to fall 500 meters.

12m

step-by-step explanation:

square root means have of a number so have of 3 is 1.5 then multiply it by 8 and you get your answer!
